To tZZ whom it may concern,.-

' Be it known that I, GEORGE B. RoB1soN,a citizen of the United States, residing at Mount Vernon, in the county of Knox and State of Ohio, have invented certain ne7 and useful Improvements in Oarbureters; andIdo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which ro it appertains to make and use the same.`

This invention is designed to provide a carbureter of novel construction for use in connection with apparatus for heating the rims of locomotive and coach Wheels, for straightening bent frames, braces, and axle-expanding cylinders, and for heating boiler-plate and articles requiring to be subjected to a uniform and high temperature. In this class of apparatus great difiiculty has been expe- 2o rienced in getting sutiicient flame When a great amount of heat is required for concentration upon a comparatively-small article or` to be distributed over a large extent of surface. To meet this difficulty in a simple and effective manner is the chief feature of the invention. 1 y A further purpose ofthe invention is to regulate the air-pressure within the tank and to prevent explosion of the said tank from 3o back draft from the burner; also, to guard against loss of pressure in the tank in the event of la mishap to the air-compressor or the pipe conveying such air to the tank.

The foregoing are some of the chief features of the invention; but other advantages are contemplated and will appear in the course of the su bjoined description, reference being had to the drawing hereto attached, which is a detail sectional view of the hydrocarbon- 4o tank and the several pipes, valves, and parts coperating therewith.

Corresponding and `like parts are referred to in the following description and indicated in the drawing by t-he same reference characters.

The tank or reservoir 1 for containing the gasolene or other hydrocarbon may be of any desired formation,and is provided at its lower end with a valve-controlled drain 2, and has 5o a hand-hole 3 in its side, closed in the usual manner. This tank or reservoir is nearly .filled with excelsior or similar light material for absorbing to a greater or less extent the gasolene or hydrocarbon supplied to the tank and utilized for carbureting the air forced therein and consumed at the burner after it has been carbureted. A gage 4 is provided at one side of the tank to determine the level of the hydrocarbon within the reservoir. A pipe 5 extends Within the tank and is in com- 6o munication with the means for supplying air under pressure, and this pipe terminates a short distance from the bottom of the tank and communicates at its upper end with a reducing-valve 6 of ordinary construction, 65 whereby the pressure of the intlowingair is regulated so as to maintain a nearly-uniform pressure Within the tank. The air-pipe 7, havingA connection at its outer end with the air-pump or air-compressing mechanism, is 7o attached to the reducing-valve 6 and is provided with a controlling-valve S and a checkvalve 9, the latter being located at a point between the controlling-valve 8 and the-pres sure-'reducing valve 6 and serving to prevent 75 the escape of air from the tank in the event of injury to the air-supplyingpipe 7. The outoWing-pipe 10 communicates with the upper portion of the tank, as shown at 11, and is provided at any convenientpoint in its length 8o i with a drain-cup 12, of ordinary construction, having a plug-controlled opening 13, through which the gasolene or hydrocarbon is supplied to the tank when the latter requires replenishing and through which the displaced air es 85 capes. A controlling-valve 14C and a checkvalve 15 are located in the length of the outiowingpipe 10,the valve 14 bein g designed for regulating the amount of carbureted air to be supplied to the burner in a given time and 9o the check-valve 15 preventing any iiame from the burner passing into the tank and causing an explosion. A iexible or hose pipe 16 connects the pipe 10 with the burner and enables the latter to be moved to anyposition within the length of range of adjustment of said pipe 16. A pressure-gage 17, of any desired pattern or make, is applied to the tank in order to determine the amount of pressure therein.

Upon closing the valve 14 and removing the plug 13 hydrocarbon can be supplied to the IOO -bureted and escapes from the upper portion ofthe tank through .the opening 11 into .the pipe 10 and passes to the burner through the pipe 16, where it is consumed. The volume of gas passing from the tank has frequently been found insufficient for many Purposes. Hence the following means have been ...def vised for increasing the-quantity of gas avail; uble for consumption .at the burner:

The means ,for addingte the flame fof the gaseous mixture Consists ef e pipe 18, .enter- ,v ingthe tank jl and extending to with-ina short distance of the bottom thereof, ,a sight-feed:

19 ,a co.upling for journaling the pipe 1-8to the outflewing-pipe at e peint intermediate lofthe check-valve 15 and the ,controlling-valve i4, a Echeck-valve 20, and a controlling-valvezl, the'latter :regulating and determining the; amount of hydrocarbon to besupplied 4tothe f carbureted air in its passage to the burner. 1

'UpQn nopening the valve 21 to the ldesired--egxtent the pressure within the tank will cause a .quantity of the hydrocarbon -to passthere'- frornthrough the pipe 1S and sight-leed 195 intOzgthe pipe l0, wherein it will be ztaken `.up-by;

.p so

the :current ,of c-arbureted air and Carried `to 1 the burner and increase the fname by adding i: tothe :volume of the gas. The hydrocarbon is supplied to the pipe 10 i-n small quantities i and is'vaporized by the current of'gas in :the s vpipe y10 and causes the gaseous mixture fto b eT E come supersatumted. Them-lid ses .eem-ing in contact 'with the heated surface .of the burner is Vincreased in volume by the flash.- ing ,action occasioned by the contact .of the-f vapor-laden gas with V.thegheated walls ofthe burner, this `action being intensified by rea-w son -of the volatile nature .ofthe hydrocarbon.

When the valve v2l is closed, thecarbureted air `passing -fromthe tank will be supplied to the burner without being enriched, as would f be the case if the valve -21 were opened to at greater or less extent.

` The burner 22 is of circular outline, audi.

consists .of a tube or pipe bent into'curved i and the `outer end portion of the pipe is conpled toa water-main .or other' means for sulpplying -a cooling agent.V As sh0wn,z.a. valve 26 is coupled to the outer end portion of tlie pipe 10 and the water-main or other means for supplying a cooling agent is connected to .the nipple of the yalve 26 .by means of a hose' or other pipe;

Hav-ing -thusdescribed the invention, what is claimed as new is-4 1. In apparatus of the character specified, the combination with a tank or reservoir for containing hydrocarbon, means for supplying Vair under pressure .to said tank and an outlowing-pipein communication with said tank for-conveying ythe carbureted or gaseous mixture to the point of consumption, of means connected with the .tank yforsupplying hydro- QarfbOll t0 the gasbut'flow pipe and .enrich-ing and increasing .the volume .of available gasat the point of consumption, substantially asV set lforth.
